NI GPIB-USB-HS+ on debian 10 (buster)

Dear linux-gpib,

I am trying to install a GPIB-USB-HS+ board on a newly install debian 10 
(buster). Note that I successfully configured a GPIB-USB-B device already.

Here are the output of some commands that may be helpful in 
understanding the issue.

uname -a
Linux *hostname* 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5+deb10u2 
(2019-08-08) x86_64 GNU/Linux

gpib_config
failed to bring board online
failed to configure board
main: No such device

When I try to load the driver manually:
fxload -D /dev/bus/usb/001/017 -I niusbb_firmware.hex -s niusbb_loader.hex
can't modify CPUCS: Broken pipe

Note that those .hex files are the exact same used for the GPIB-USB-B 
adapter that works.

Thank you in advance for the help.

Regards,

Bruno
